LOUIS THEODOR KARRAS, OF DRESDEN, SAXONY, GERMANY.

POT-LIFTER.

SEECIFIOATION forming part of Letters Patent No. 340.126, dated April 20, 1886.

Application filed February 1, 1886. Serial No. 190,524. (No model.)

To all whom it may concern:

Be it known that I, LoUIs THEODOR KAR- RAS, of the city of Dresden, in the Kingdom of Saxony and German Empire, have invented certain new and useful Improvements in Pot- Lifters, and of which I declare the following to be a specification.

My invention relates to improvements in pot-lifters or apparatus for lifting orhandling pots, smeltingvessels, crucibles, or other vessels in heated state without injury or inconvenience to the operator. In order to effect this purpose, I employ an instrument constructed on the principle of a pair of tongs or shears, the arms of which are at the one end provided with suitable claws corresponding to the form of the handle of the vessel, while the other ends are provided with suitable handles. The arms are held open by means of an appropriate spring wound or bent around the axis or pivot of the instrument and pressing with its ends against the arms or legs carrying the handles. To the axis or pivot of the said instrument I also apply two stays or arms, which run in downward inclined direction toward the vessel to be lifted from the fire, so as to hold the same in correct position.

A bellshaped protector can be placed over the instrument, so as to protect the hands of the operator from the heat radiating from the hot vessel.

This pot-lifter can be applied to great advantagein technical establishments, iron-founderies, chemical, and other factories, as the same prevents the hands of the operator from being scalded by any matter boiling over in the aforementioned bell shaped protector.

Figure l is a side elevation of my improved pot-lifter with smelting-pot and the stays e supporting the said pot. Fig. 2 is a view of the lower side of the instrument or pot-lifter with the washer and bolt-head for holding the spring and the stays removed. Fig. 3 is a side elevation of my improved instrument or pot-lifter with bell-shaped protector g in crosssection.

a a are the two longer arms or grippers with the claws b, which can be made of one piece with the said arms or be attached to the same in appropriate manner, and preferably of such form that they correspond with the form of the handle to the vessel to be held by the same.

0 c are the handles of the pot-lifter.

d is the axis or pivot around which the handles and arms of the said pot-lifter turn.

0 e are two stays, which are made from one piece of metal and stationary, as shown in the accompanying drawings. The said stays care held rigidly in position by means of two bolts, it, which are at the one end fixed in a heart or other shaped piece of metal, h, and at the other end in the stays e e. In this case I prefer to bend up the one end or side of the sheet metal, so that the same acts as support or handle for the hand-protector, which can be held rigidly attached to the said holder by means of suitable screws.

fis a spring, which is laid around the axis or pivot d in such manner that the ends of the same press against the inner surface of the handles 0, so as to hold the latter apart.

9 is a bell-mouthed protector, which is attached to the holder h or held in other suitable manner, and serves to protect the hands of the operator against the radiating heat or splashes of heated matter.

It is a piece of sheet metal, which is fitted to the bolt, axis, or pivot d, serves to receive the bolts k, for holding the stays e, and is provided with an inclined upward-projecting part, as shown in Fig. 1, which can be employed as bearing for the bell-mouthed hand-protector.

The stays 6 can be made adjustable, so as to enable my improved pot-lifter to be used for pots or other similar vessels of various sizes.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is In a pot-lifter or instrument for handling pots, crucibles, and other vessels, the combination of the arms or legs a a, the claws b, handles 0, and bell-mouthed hand-protector g,

with the stays e e, substantially as and for the 9 purpose described in the foregoing specification and shown in the accompanying drawings.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

LOUIS THEODOR KARRAS.
